设备更新分析中动、静态关系一致性研究

Research on the Convergence of Static and Dynamic Relationship for Equipment Replacement

根据设备残值和年运行费变化所作的合理假设 ,提出四个动态、静态更新模型并获得相应的解 ,进而对这些模型和解的统一性问题作了理论上的探讨 ,证明静态模型及其解是动态情况的一种特例 。

Based on reasonable assumptions of equipment salvage and annual operation cost,four dynamic and static models for equipment replacement are established, and their solutions are found.The convergence of the models and solutions are analysed in detail from the theoretical point of view.The conclusion is that the static model and solution is a special case of dynamic models and their solutions.The research presents a new approach to the study of some complex problems for equipment replacement.
